i want to put the shim and head kit on my 2001 machz i was woundering if the head that thay sell with the kit was a stock head that is just cut the thickness of the shims because i have an extra head from a 97 machz. could i use that head by just cutting it and ordering the shims or do the chambers have to be reworked !!!

The chambers have to be re-worked. You can send the head to the Crankshop if it's the same as your 01 and they will modify it for $38.00 USD. I would also get the aluminum spacer that uses 2 base gaskets as opposed to the thick base gasket.
I did this to my 01 and had the middle cyl. bearing go bad.. Not sure if the shim kit caused it but I put it back to stock..
I think a 10 thou. cut of the head would be a better way to go for a little extra power.
IMO.

Good luck.
